− | ==What is Vacuum Forming?==
| + | 13A |
− | Vacuum forming is a thermoforming manufacturing method used to shape plastic.
| + | 115V |
− | | |
− | *A mold is placed on a surface that contains many small holes
| |
− | *A sheet of plastic is clamped in a frame and heated until soft
| |
− | *The hot plastic is pulled over the mold, and a vacuum sucks through the small holes and forms the plastic over the mold
| |
− | *The result is a plastic impression of the mold’s contour
| |
− | | |
− | Vacuum forming can be used to mass produce functional items such as plastic packaging, and for creative works such as resin molds and costume pieces.

| |
− | The default frame size of the Nichols Model 10-B is 14" x 20", and thermoplastic material will need to be this exact size.
| |
− | | |
− | There are plans to create removeable frame inserts to allow for smaller, more standard sizes of material. This will reduce plastic waste and also increase the vacuum power.
| |
− | | |
− | Recommended material thickness is 0.02” to 0.06”(approx. 0.5mm to 1.5mm). Most types of thermoplastic will work, but these types are recommended:

− | LDPE (low density polyethylene) is not recommended as the machine cannot heat the plastic hot enough to mold.
